All U.S. Navy submariners are volunteers. At the Naval Submarine School
in Groton, Connecticut, they first learn the basic skills required to
operate the complex equipment that fills a modern submarine. They also
learn to deal with such emergencies as flooding and fire. They then proceed
to more advanced training in their specialties. The Nuclear Power School,
for instance, lasts a full year and includes both classroom and hands-on
instruction.

But there is still
a long way to go for the would-be submariner. Upon graduation, sailors
are assigned to a submarine, where they enter a rigorous qualification
program that may last as long as nine months for enlisted men, up to two
years for officers. Only after passing a tough final exam that requires
them to operate most of the ship's systems do they receive the coveted
dolphin insignia of the qualified submariner.
